and throwing all 99 of my pounds around.
I have highest level security with my employer and act *daily* to protect vital personal information available to me from the people I serve, some of whom are NAMES you'd recognize in the entertainment industry.
Trust me, except for some of THEM, who are duly paranoid, most people aren't as proactive as they should be (and so, in their stead, I AM) about the measures THEY need to take in order to protect the security of that information, e.g., name, contact addresses, phone #, account #, etc.
THUS
if I were the OP, I'd be:
(a) hopping mad that contact information I submitted on a survey was NOT kept confidential as evidenced by email (personal, I gather) received from an FA; AND
(b) writing the air carrier to that effect, especially if I had surrendered that contact information in the survey with the air carrier's expressed promise of confidentiality thereon;
(c) informing the air carrier I would be happy to participate in future such surveys only if I could be assured of confidentiality, and not otherwise.
But maybe that's just me.
Anyway, I *do* write letters!
Obviously.
